摘　　要：The absorption of Pb(Ⅱ) ions from aqueous solution by different alginate compounds was studied in a batch sorption system.Water soluble sodium alginate and insoluble calcium alginate beads were investigated.The lead-binding capacity of both alginate compounds was highest within the pH range 6-8.The binding capacities and rates of Pb(lI) ions by alginate compounds were evaluated.The Langmuir,Freundlich,and Bruneaur,Emmet and Teller (BET) sorption models were applied to describe the isotherms and isotherm con...The absorption of Pb(Ⅱ) ions from aqueous solution by different alginate compounds was studied in a batch sorption system.Water soluble sodium alginate and insoluble calcium alginate beads were investigated.The lead-binding capacity of both alginate compounds was highest within the pH range 6-8.The binding capacities and rates of Pb(lI) ions by alginate compounds were evaluated.The Langmuir,Freundlich,and Bruneaur,Emmet and Teller (BET) sorption models were applied to describe the isotherms and isotherm con...
